VERSION 2 ENHANCEMENTSThis second revision device now has a membrane ON/OFF switch,
USB bus power has been increased up to 1.5 amps to drive a wider range of USB storage devices and transfers at speeds up to 90% of the native USB device's rate as measured by using TIM (Tableau IMager).

Like other UltraBlock forensic bridges, the USB Write Blocker supports both USB 2.0 and FireWire400 connections to a host computer, permitting flexible operation with the full range of forensic hosts and existing software tools. The UltraBlock USB Write Blocker is designed to allow forensically sound images to be extracted from USB mass storage devices. Data can be read from the USB mass storage device without fear that data on the USB device will be modified inadvertently during the acquisition process.

NOTE: There is an important difference between the UltraBlock USB Write Blocker and our other UltraBlock products. The IDE, SATA, and SCSI (discontinued) forensic bridges can be field-switched between read-only (write-block) and read-write modes of operation, the UltraBlock USB Write Blocker is permanently configured for write-blocking operation.
